== 1.2 Downloading the Patch(es) ==

the latest 'released' patches can be downloaded from > http://www.13thfloor.at/vserver/ experimental patches > can be found at http://vserver.13thfloor.at/Experimental/

<code>

# wget http://www.13thfloor.at/vserver/d_rel26/v1.9.3/patch-2.6.9-vs1.9.3.diff.bz2

...

</code>

== 1.3 Unpacking the Kernel ==

the kernel source can be unpacked anywhere, but given > that you have enough disk space /usr/src is a good place.

<code>

# tar xjf linux-2.6.9.tar.bz2

</code>

== 1.4 Applying the Patch ==

the simplest way is to make a 'shallow' copy of the > unpacked source tree (a bunch of hardlinks) which will > not use up significant diskspace, but might help if > you want to change the patch or check for differences.

<code>

# cp -la linux-2.6.9 linux-2.6.9-vs1.9.3

# cd linux-2.6.9-vs1.9.3

# bzcat ../patch-2.6.9-vs1.9.3.diff.bz2 | patch -p1

</code>

= 2. Configuring the Linux Kernel =

</code>

== 2.2 Default Config ==

</code>

= 3. Building the Linux Kernel =
